Title: D type flip-flop
Inventor: KONDO TOSHIO
IPC: H03K3/037
Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To shorten a hold time, speed up operation, and lower power consumption by connecting two stages of master-side latches, which function to hold only a low level, in series. SOLUTION: The master-side latches A and B both hold only the low level. Then the output node 12 of the master-side latch A is connected to the input node 14 of a slave-side latch C and also connected to the input node 13 of the master-side latch B. Consequently, a high level and the low level are both held at the output node 12' of the master-side latch B. Therefore, even if input data at an input terminal D varies from the high level to the low level after a clock signal CLK varies to the high level, the high-level signal held at the output node 12' never disappears and write to the slave-side latch C which is carried out through a transistor 6 as a 2nd data transmitting means is never interrupted right after the clock signal CLK goes up to the high level.

Title: Production of superconducitng material
Inventor: YAMADA YUTAKA
IPC: C01G1/00
Filed: 1987-10-20
Abstract: PURPOSE:To obtain a superconducting material at a low cost, by using a raw material consisting of crude rare-earth metals of a state before separated and purified into each constituent element, mixing the material with BaCO3 and CuO, calcining the mixture and separating and collecting the part exhibiting superconductivity. CONSTITUTION:A rare-earth metal mixture (e.g. a mixture of Dy, Ho, Er, Tm, Yb, etc.) before being separated and purified into each element is used as a raw material. The rare-earth metal mixture is mixed with BaCO3 and CuO and calcined. The part exhibiting superconductivity is exclusively separated and collected e.g. by taking advantage of the critical temperature difference to obtain the objective superconducting material. The superconducting material can be produced at a low cost because the expensive purification process of the rare-earth metal is omitted in the present process. A superconducting wire can be produced by applying the obtained superconducting material 2 to a thin core rod 1 made of Cu or Al and calcining the product.

Title: Manufacture of flexible printed wiring board
Inventor: OTANI SHIMIZU
IPC: H05K3/28
Filed: 1987-10-20
Abstract: PURPOSE:To improve elasticity and solder reflow resistance, by performing oxidizing treatment of the surface of a copper circuit. CONSTITUTION:The surface of a copper circuit, which is formed with etching, undergoes oxidizing treatment with oxidizing solution. As the oxidizing solution used for the oxidizing treatment, a mixed liquid, in which additive is compounded into sodium chloride, sodium hydroxide and trisodium phosphate, is used. Before the surface of the copper circuit undergoes the oxidizing treatment by using the oxidizing solution such as this, the surface of the copper circuit undergoes soft etching to a depth of 0.5-2.0mum by using soda persulfate based or iron chloride based soft etching agent, and thereafter the oxidizing treatment can be performed. Thus, elasticity and solder reflow resisntance can be improved.

Abstract: PURPOSE:To make it possible to constitute the portable bankbook registering terminal printer concerned, which can exactly print the transaction contents in the respective register columns of a bankbook, by a method wherein printing is started after pulling the bankbook in to the desired printing starting line from the reference position, when the tip part of the bankbook is judged to be at the reference position. CONSTITUTION:Upon the pointing of printing starting, a stepping motor rotates by the predetermined amount in accordance with the memorized controlling program so as to transfer a clamper 28 together with a bankbook 151 to the direction of the depth of a printer and, after that, stops once so as to detect the presence and absence of the bankbook with a first sensor and confirm whether the bankbook is clamped under regular state. Next, when the bankbook 151 is judged to be clampe under regular state, the motor is rotated by the predetermined amount in accordance with the memorized controlling program so as to move the bankbook in order to coincide the line next to the printed line recorded in the magnetic stripes of the bankbook read in advance with the heating part 106 of a printing head 101. In this case, when there is no slip between a platen low 15 and the bankbook 151, the predetermined printing is carried out in accordance with the controlling program.

Title: Circular induction accelerator for piercing logging
Inventor: FUERITSUKUSU KEI CHIEN
IPC: H05H11/00
Filed: 1991-10-14
Abstract: PURPOSE: To generate a flux of high energy gamma rays photons by accelerating electrons up to a required energy and beam current, and thereafter, upsetting betatron conditions again so that the electrons collide with a target. CONSTITUTION: Electrons injected into an acceleration chamber 16 are trapped therein by an applied magnetic field, are guided along a nearly circular starting route until reaching a required end point energy, and are extracted outside from the circular orbit. The electrons are injected into a vacuum chamber 16 by an injector 26 extending via a boat in the acceleration chamber. Soon after its injection, betatron conditions are established again although they are upset at the injection time, and the electrons are arranged so as to take an nearly circular orbit 24 in the acceleration chamber 16. After the electrons are accelerated up to the required energy and beam current, the betatron conditions are again upset so that the electrons collide with a target 28, and at that time the flux of high energy gamma radiation photons are generated.

Title: Hair growing device with bag
Inventor: TAKIMOTO KAZUYUKI
IPC: A61H7/00
Filed: 1987-10-20
Abstract: PURPOSE:To circulate blood in a top portion of the head forcibly. and continuously for a long time, by mounting an inner volume variable bag on the top portion and repeating air feeding/exhausting to give to the top portion cyclic motions of pressing and releasing. CONSTITUTION:A cap 3 is placed over the head 1, and air-tight bag 4 at the top of the cap 3 is connected to an air feed/exhaust unit 6 via a hose 5. When air is supplied to the bag 4 from the unit 6 via the hose 5, the bag expands, presses the top portion, pushes down capillaries on both sides of subcutaneous artery 7 and vein 8, and drives blood therein toward sides, front and back portions of be head to discharge blood temporarily out of the top portion. When the air is exhausted from the hose 5, pressure in the bag decreases to allow blood to flow to be top portion from be vein 7 but blood in the artery 8 stays small in amount because the blood can not be carried reversely due to a check valve in a blood vessel. Thus, blood in the top portion can be always kept fresh to make hair on the top portion thick and young.

Title: Power steering system
Inventor: KACHI HIROSUKE
IPC: B62D117/00
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To provide a power steering system that allows a steering wheel to smoothly return to the steering middle point as well as improve fuel efficiency. SOLUTION: In case of steering in the direction away from the steering middle point, the threshold value between the steering speed range where an electric motor is rotated at the first rotational speed R1 and the steering speed range where the motor rotational speed is changed substantially linearly in accordance with the increase in the steering speed is set to the first lower limit value WL1. In case of steering in the direction toward the steering middle point, the threshold value is set to the second lower limit value WL2 that is larger than the first lower limit value WL1.  As a result, the characteristic line P2 referred to set the motor rotational speed R for steering toward the steering middle point is defined by moving the characteristic line P1 referred to set the motor rotational speed R for steering in the direction away from the steering middle point in parallel thereto. The steering speed value corresponding to each motor rotational speed during steering in the direction away from the steering middle point becomes larger than that in the direction toward the steering middle point.
